🔧 Highlander - Engine Oil and Oil Filter Change

Your Highlander uses a cartridge-style oil filter, meaning the replaceable filter element sits inside a reusable housing. Drain the old oil, replace the cartridge and sealing rings, refill with SAE 0W-20 full-synthetic oil, and reset the maintenance reminder.

Difficulty Level: Beginner | Estimated Time: 45-60 minutes

⚠️ Safety & Precautions

• ⚠️ Work on level, solid ground and never crawl beneath a vehicle supported only by a jack.
• ⚠️ Allow the exhaust system to cool enough that it cannot burn you, but keep the oil slightly warm so it drains well.
• ⚠️ Wear gloves and safety glasses because used engine oil can irritate skin and splash unexpectedly.
• ⚠️ Keep the engine off while underneath your Highlander.
• ⚠️ Do not overtighten the plastic oil-filter housing; it can crack and cause rapid oil loss.
• ⚠️ Battery disconnection is not required.

📋 Before You Begin

• 📍 Park your Highlander on level pavement, shift into Park, apply the parking brake, and chock both rear wheels.
• 🌡️ Run the engine for three to five minutes, then shut it off and wait several minutes. The oil should be warm, not dangerously hot.
• 🧴 Open the hood and loosen the engine-oil filler cap. Pull the dipstick slightly upward to help the crankcase drain.
• ♻️ Prepare a sealed container for the used oil. Take it to an authorized oil recycler or service facility; never pour it onto the ground or into a drain.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Secure the Front

• Place the 2-ton wheel chocks firmly against the front and rear faces of both rear tires.
• Use the 2-ton floor jack at the reinforced front-center lifting point on the front subframe.
• Position the 2-ton jack stands beneath the reinforced side support points, then lower your Highlander onto them.
• Gently push the vehicle to confirm it is stable before going underneath.
• Never trust a hydraulic jack by itself.

Step 2: Open the Lower Access Area

• Put on the nitrile mechanic gloves and ANSI Z87.1 safety glasses.
• If the lower splash shield blocks access, use the 10mm socket, 3/8-inch-drive extension, and 3/8-inch-drive ratchet to remove its fasteners.
• Set the shield and fasteners aside in installation order.

Step 3: Drain the Engine Oil

• Place the 8-quart oil drain pan beneath the oil-pan drain plug. Position it slightly toward the rear because the first stream can travel several inches.
• Use the 14mm socket and 3/8-inch-drive ratchet to loosen the drain plug counterclockwise.
• Finish removing the plug by hand while pressing it inward, then pull it away quickly.
• Let the oil drain until it slows to an occasional drip, usually 10-15 minutes.
• Remove the old crush washer and install a new drain-plug crush washer.
• Thread the plug in by hand first. Use the 14mm socket and 3/8-inch-drive torque wrench to torque to 40 Nm (30 ft-lbs).

Step 4: Drain the Oil-Filter Housing

• Move the 8-quart oil drain pan beneath the cartridge-filter housing.
• Use the square drive of the 3/8-inch-drive ratchet to remove the small center drain cap from the filter housing.
• Remove the old small O-ring from the cap using your gloved fingers. Do not scratch its sealing groove.
• Push the Toyota-style oil-filter drain adapter straight into the housing opening and let the trapped oil drain completely.
• Remove the adapter. Lubricate the new small O-ring with clean 0W-20 oil and place it in the drain cap’s proper groove.
• Use the 3/8-inch-drive torque wrench to torque the filter-housing drain cap to 13 Nm (10 ft-lbs).

Step 5: Replace the Filter Cartridge

• Fit the 64mm 14-flute cartridge oil-filter wrench fully onto the filter housing.
• Use the 3/8-inch-drive ratchet and 3/8-inch-drive extension to turn the housing counterclockwise.
• Lower the housing carefully because it may still contain oil.
• Pull the old filter cartridge straight out and remove the large housing O-ring using your gloved fingers.
• Clean the housing with absorbent shop towels. Do not use sharp tools on the sealing surfaces.
• Lubricate the new large O-ring with clean 0W-20 oil and install it in the designated housing groove, not against the threaded edge.
• Press the new cartridge fully into the housing.
• Thread the housing into the engine by hand. If it does not turn easily, back it out and start again.
• Use the 64mm 14-flute cartridge oil-filter wrench and 3/8-inch-drive torque wrench to torque the filter housing to 25 Nm (18 ft-lbs).
• The O-ring seals it; extra tightening does not.

Step 6: Reinstall the Lower Shield

• Use the 10mm socket, 3/8-inch-drive extension, and 3/8-inch-drive ratchet to reinstall any removed splash-shield fasteners.
• Snug the small shield fasteners evenly without crushing the plastic.
• Use the absorbent shop towels to wipe oil from the drain-plug and filter-housing areas so fresh leaks will be easy to identify.

Step 7: Lower the Vehicle

• Use the 2-ton floor jack to raise your Highlander slightly off the 2-ton jack stands.
• Remove both stands and lower the vehicle slowly onto level ground.
• Leave the 2-ton wheel chocks installed until the work is complete.

Step 8: Add New Engine Oil

• Place the automotive funnel with 1-inch outlet in the oil-filler opening.
• Add approximately 4.3 US quarts of SAE 0W-20 full-synthetic engine oil, then reinstall the filler cap.
• Start the engine and let it idle for about 30 seconds. The oil-pressure warning light should turn off within a few seconds.
• Shut the engine off immediately if the oil-pressure light remains on.
• Turn the engine off and wait five minutes on level ground.
• Remove the dipstick, wipe it with an absorbent shop towel, insert it fully, and remove it again.
• Add oil gradually through the automotive funnel until the level is near the upper dipstick mark. Total capacity is approximately 4.6 US quarts (4.4 liters) with the filter.
• Do not overfill above the upper mark.

Step 9: Reset the Maintenance Reminder

• Switch the ignition on without starting the engine, then use the instrument-panel trip button to display Trip A.
• Switch the ignition off.
• Press and hold the trip-reset button.
• While holding the button, switch the ignition back on without starting the engine.
• Continue holding until the display’s countdown finishes and the maintenance data resets, then release the button.
• Start the engine and confirm the maintenance reminder no longer appears.
